Big Data applications - EFFORTE Business Forum

  1. 1. Big Data applications Efforte Business Forum Erik Willén, Isabelle Bergkvist
  2. 2. Objectives Describe potentials in using, refining and linking existing and new Big Data sources in forestry applications, and evaluate the identified sources of data through a SWOT analysis. Based on these data, create decision-support models for efficient, sustainable and value-creating forestry and forest operations. Demonstrate the potential in keeping and refining information throughout subsequent operations in the forestry process. Validation and pilot tests of project results in relevant environment (hosted by partner companies).
  3. 3. Outlook on Big Databases - forest planning Detailed digital elevation model Soil maps VHR imagery Mobile laser scanning Weather data and models Lidar based forest estimates Road databases Forest machine data

  17. 17. Conclusions  Operational use of trafficability maps and tools to extract main extraction routes  Digital elevation model spatial resolution critical  Important to act pro-actively to secure data collection  Interesting potential to use Can-Bus data to for trafficability mapping – other options also availible (drones, machine-mounted equipment, ..)  Big data applications opens a wide range of possibilites for research and applications – standardisation crucial!  Previous research now possible to implement with Big Data Streams  Forest machine data key for many applications – start collect standardised data!
